LOOSE-LEAF BINDER. I

Specification of Letters Patent.

' Application filed lilarch 19, 1920. Serial Ito. 367,148.

To all whom it may concern: i

Be it known that I, ERIC C. MOORE, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, fioation, and to the marked thereon.

y present invention relates to station cry and more particularly to loose leaf binders embodying covers or holding members and separate perforated leaves secured therein by impaling posts from which they may be detached at will and the invention has for its object to provide a binder of this nature in which certain of the impaling devices characterized as transfer members, may be removed with or without leaves that it may be desired to transfer with them, from either side of the binder, that is, by lifting either cover. To these and other ends the invention resides in -.certain improvements and combinations of parts all'as will be hereinafter more fully described, the novel reference-numerals features being pointed out in the claims at the endof the specification.

In the drawings: 7

Figure 1 is an end view of a closed binder constructed in accordancewith and illustrating one embodiment of my invention;

Figure 2 is an enlarged fragmentary sectional view taken transversely through the same near its center, with the leaves removed;' I

Figure 3 is an enlarged longitudinal sectional view taken substantially 0n the line 3-3 of Figure 2;

Figure 4 is a detail side view of one of the transfer members, and

Figure 5 is a fragmentary plan view of one of the leaves and adjacent impaling devices of the cover;

Similar reference numerals throughout the several views indicate the same parts.

Loose leaf binders 0f the kind here involved have hitherto been made with two sets of impaling posts, one set permanently secured to one cover member and the other set, in a relatively reverse position, detachably arranged on the other side of the pile forming a part of this speciof leaves and just beneath the other cover member. The last mentioned set of impaling posts constitutes a transfer member by means of which any desired number of the leaves may be removed together from the binder while held in register with each other, so that they may be replaced with similar ease but in order to accomplish this removal or replacement, it has been necessary to see that the binder is lying on that cover member paling devices and it has been possible to remove only the uppermost leaves or, at least, necessary to remove them first. In the practice of my present invention. it is possible to remove sheets from either side of the pile, selectively, with equal ease.

eferring more particularly to the drawings, I have shown my improvements embodied in a familiar type of binder embodying a back A and cover members B and C hinged thereto at D. The cover members each comprise a connecting portion E to which the body of the coveris hinged at F. The hinges F are utilized in the ordinary use of the book to open and close the covers while the leaves are held ti htly together and the connecting members and back A are, for the time, in fixed relationship. The hinges D are utilized only in further opening the binder through the release of looking elements hereinafter described, to make changes in the dispositions of the leaves. Both sets of hinges D and F are preferably constituted by the ornamental leather or similar flexible covering for finishing the parts indicated at G in the sectional views.

he connecting members E of the covers are similar in structure so far as the features thereof are concerned and differ in detail only in the location of the sockets for the impaling posts and therefore a description of one will suffice forboth. In the construction of each, two inverted sheet metal channel members 1 are reversed with respect to which carries the fixed im-' each other and placed with their flanges overlapping to provide a box-like housing and and against the said outer channel member WhlCll it is confined by guide pins thereof to 'ing.

4 is a lock or bolt 5 having a projecting operating portion or finger-piece 6 at one end thereof extending to the exterior of the hous- The bolt is perforated or cutaway at the points 7, 8 and 9, corresponding approximately with the sockets 2 and 3 and in connection with the perforation 9. a locking shoulder 10 is formed adjacent the socket 2. A suitable spring 11 connected to the bolt and to the housing, tends to hold the locking shoulder' 10 opposite the socket 2 to engage an element occupying the same. The locking shoulder is moved beyond the socket against the tension of the spring 11 by ressing inwardly upon the operating memer 6 at the end of the binder. The movement of the bolt under the influence of the ,sgring is limited by the engagement of an a utment 12 thereon with a stop 13 on the housing.

Superposed upon the inner side of each housing and lying fiat against the same are two transfer bars 14 and 15 having fi-Xed thereto spaced impaling posts 16 and 17, the respective pairs of posts being so arranged on their carriers that one set fits between the other set, as shown. The loose leaves H fit these impaling posts and are held in reg1ster thereby, as shown in Figure 1. The posts extend to the opposite connecting member E from that against which their carrying bar is disposed and occupy the sockets- -other binder in' which they do not belong.

For instance, in one binder, the irregular or finned posts 17 would be at the ends of the perforations of the leaf 8 and the cylindrical ones 16 in the center, whereas in the other binder, the positions of' these pairs would be reversed.

The parts cooperate in this way to form the binder and accommodate the leaves but so far, nothing has been described to bind the cover members and their connecting portions E together and clamp the leaves or retain them against the disengagement of the impaling members 16 and 17 from the covers. The means I employ for this purpose consists, in the present instance, of a separate post- 19, not an impaling post, preferably arranged centrally of the row of other posts and of the longitudinal extent of the connecting members, and to accommodate which the leaves 8 are preferably cutaway, as shown at 20 in Figure 5, so that they the leaves.

the retaining post project" into the socket 2 of the connecting members E and are normally locked snugly to the connecting members by the engagement of the shoulders 10 on the bolts 5 with shoulders on the posts formed by notching the tips as shown at 23 in Figure 3. The rounded ends of the tips, when inserted in'the sockets, preliminarily displace the locking shoulders, thus rendering the bolt an automatic or spring lock.

The operation and use of the device will be clear from the above description. If it is desired to remove leaves or to open the binder from the top with it disposed as in the figures and the cover B uppermost, the bolt 5 of that cover member is pressed in and the cover thrown back on the hinge D instead of the hinge F. The connecting post 19 is then relieved from the bolt to be drawn from the socket 2 and there is at no time anything to prevent the withdrawal of the connecting member from the ends of the upstanding impaling posts 16. The transfer bar 15 with its downwardly extending impaling posts 17 is left lying on the pile of leaves or on the shoulders 21 of the post 19 and is free to be raised from the latter and from the impaling posts lohtogether with such of the leaves as it is desired to hold on the posts 17 as they are withdrawn upwardly from their free engagement.with the lower connecting member E. The connecting post '19 remains in place and to prevent the lower transfer bar 14 from having a tendency to pivot On the connecting post 19 by which it is held, I provide short centering projections 24 thereon that cooperate with apertures or recesses 25 in the connecting member. In the present instance, these projections are supplied by shallow rounded extensions on the butt ends of the impaling posts. The parts are returned in reverse order and the cover again locked with the connecting post 19 by simply pressing down on it.-

The same method is pursued if the book is to be opened from the other side for the removal of those leaves which. in the prior instance, were the bottom leaves of the pile. The transfer member 15 remains attached as the primary impaling element of the ordinary binder and the transfer bar 14 with the posts 16 isthe one that is lifted off with In no case is it necessary to re-. move the connecting or locking post 19.
